I followed the info videos on testing temp sensor and both heating elements and they are within limits. The oven does not reach set temperature. It varies between 25f and 50f too low. Example: set oven to 350f and a thermometer I purchased to place inside oven shows 325f. What is the next test I do to find out what part I need to replace.
If your sensor and elements are good, the main control that turns the elements on and off would be the problem. EBR89295701 Main Pcb Power Control Board Assembly | Genuine Lg OEM In Stock
